IMPROVEMENT IN TUBE-WELLS.

TO ALL WHOM IT MAY CON CERN Be it known that I, DWIGHT KLLOGG, Jr., of Northampton, in the county of Hampshire, and State of Massachusetts, have invented a new and ,improved Wel1-Tube; and I do hereby declare the following to be afull, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, and in whch- I Figure lis a vertical arial section of my invention, and

Figure 2 is a cross-section ot' the same. i

In this invention a removable tube or chamber, designed to be filled with pebbles, or some similar material, is employed, in connection with the well-tube, for the purpose of filtering and cleansing the water.

Similar letters of reference indicate corresponding parts in the several gures.

In the drawings, A represents thewell-tube, Vprovided with a system of vertical slots, a a, for the admission of the water. Inside of this tube I employ a removable tube or chamber, C, the walls of which are pierced with a system of slots, c c, similar in size and position, in relation to each other, to' the slots a a of the'outer I tube. The'tube C is provided with a iiange, e, around its upper end, another similar iiange, e', around it, a short distance from its lower end, and just at the bottom of the lowest slot, a, of tl1ewell-tube. Y i

The object of the iianges, acting in combination, is to hold the inner tube in a proper position for the water to enter it' freely on all sides. Another object ofthe lower iiange e is to form a shell for the reception oi' sand, dirt, and other substances that may get into the well-tube, and to enable the proprietor to remove all such obstructions by simply withdrawing the inner tube. This is accomplished by letting down into the wel1,whenever its condition requires it, a cord, having a hook attached to its lower end, a rod 'or bail, r, being xed across the centre of tube C, at its upper extremity, for the hook to catch under. The inner tube,.having been cleansed,

may be returned to its place in the same manner. In lowering it to its position, care must be taken not to bring p 1 its slots c c directly in front of the slots a a of the well-tube, but the vertical rows of slots c c are to come half Way between the vertical rows of slots a a. The upper end of the wel1-tube is marked to indicate4 the line of the slots a a, and to direct the operator in adjusting the inner tube, when it is lowered to its place.V A short conical peg projects downward from the lower end of tube C, designed to enter a. corresponding cavity in the ',iloor of the well-tube, and to assist the anges in keeping the inner tube in place. The inner tube thus constructed and situated, I fill with small clean pebbles, as shown at it', iig. 2. The object of these pebbles is 'to filter and thoroughly cleanse the water in its passage through the tube. The upper flange e closes the space around the tube C, and forces all the water to enter the slots c c and pass up through mass of pebbles.

The invention has been thoroughly tested, and found to be a great improvement upon the systemsof filtra.- tion hitherto used in connection with these wells. It is cheap, easily made and operated, never liable to get out ofrepair, and renders water perfectly sweet and clean that was previously too impure to be used for drinking or washing. t V

Instead of thc-pebbles, other substances that will operate in any equivalent manner may be used, such, for instance, as chips of wood, sticks, pieces of iron, charcoal, etc. v v K Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The removable slotted interior tube G, having the bail r and flanges e e', adapted to contain the enclosed filtering substance i t', when used in combination with the well-tube A. substantially in the manner and for the purposes specified.

To the above specification of my invention I have signed my hand, this 23d day of September, 1867.
